Letter from the UNCC Letter from the UNCC ChancellorChancellor

Project completion date– Fall Term 2001

Budget– $100,000

LocationLocation

Van Landingham and Mary Alexander Rd.

PurposePurpose

Supply two bridge designs for consideration by the Chancellor

Discuss certain advantages and disadvantages of each design and their different cost to the University

Bridge DesignsBridge Designs

MaterialsMaterials

Cement blocks for support and a brick overlay to correspond with the surrounding campus appearance.

Walkway– Cement with brick railings.

Steps – Brick and cement with a stainless steel,

mirrored finish railing.

Bridge Design 1Bridge Design 1

Design 1Design 1

Advantages

1. Very simplistic stair and walkway

arrangement

Disadvantages

1. Necessary to build two of these designs to solve the problem

2. Costly

3. Time consuming

Bridge Design 2Bridge Design 2

Design 2Design 2

Advantages

1. Single bridge that would cross both roads

2. Aesthetically pleasing

3. Cost effective

Disadvantages

1. Length must be greater than that of Design 1

Bridge Cover OptionsBridge Cover Options

Clear glass or Plexiglas– Campus can be seen in the background– There will be some additional maintenance to

keep it clean

Chain link fence – Prevents objects from falling on to the roadway

but will not offer much protection

If Bridge is Covered…If Bridge is Covered…

Ventilation System– Provide air circulation– Passing smokers will likely be inclined to stop

under the covered bridge during poor weather.

Drainage system – Prevent standing rainwater.– Tied into the sewer system to prevent any

pollution.

TimeTime

Estimated time for the completion of the project is 30 to 45 days.

Design 1 will take longer than Design 2 because more construction will be necessary.

RecommendationsRecommendations

Bridge DesignBridge Design

Design 2– Aesthetically pleasing – Cost effective for the campus – Almost identical bridge at the University of

North Carolina Campus in 1993 and no reported problems

OptionsOptions

Cover– Plexiglas top

Ventilation System

Drainage system

Construction TimeConstruction Time

During the summer – Approximately 30-45 days– Road will have to be temporarily closed– Fewer students will be on campus
